They were able to observe and determine the depth of the ocean floor and the features of the ocean floor.. Today you need to know. Explain what evidence there was to support the theory of continental drift – suggested by Alfred Wegener. Explain why the scientific community did not accept his theory. Understand how seafloor spreading provided further evidence that his theory was correct. . Chapter. 12-1. Pan-. gaea. . “. all. - earth. ” .
